Agricultural Technology & Mechanics Nebraska Career Development Event Handbook and Rules for 2018-2020 1. PURPOSE Agricultural Technology and Mechanical systems is comprised of strong technical content and complimented by the development of practical, hands-on skills. The subject matter areas and skill development practices have been grouped into three ‘systems’ areas, so named because of the complex interaction and synergistic processes common to agriculture. The term ‘system’ is used to emphasize the interactive relationship between each area of agricultural technology and mechanical systems. These three systems are: Small Gas Engines or Hydraulic/Pneumatic, Electrical, and Machines.

• AFNR Courses that align with this CDE include: Power Structure and Technical Systems and in any given themed year the following courses could be included: Agronomy, Large Animal Management, Agribusiness, Environmental Science


2. OBJECTIVES A. Team Activity:

a. The student team will compute/answer a series of questions (10 to 25) for a given scenario using provided information and actions based on the current year’s theme which is listed for each year above.

B. Individual Activities:

a. Small Gas Engines (2018, 2020)

ii. The Student Will identify specialty tools used with small gas engines from the list provided. See Appendix A

iii. The Student Will demonstrate the correct usage & reading of a micrometer.

iv. The Student Will correctly answer 25 questions about SGE safety, maintenance, assembly, theory, concluding the various systems (lubrication, ignition, carburation, etc.)

b. Hydraulic/Pneumatic (2019)

The Student Will correctly connect three electrical devices (switch, lamp, receptacle) in a circuit as illustrated in a schematic diagram in the CDE instructions (score sheet) according to NEC guidelines. Scoring criteria includes: correct wire color usage for power and neutral and appropriate screws, correct insulation removal, wires hooked clockwise around screws, amount of bare wire exposed, amount of wire and insulation inside device


box (too much or too little), following instructions (correct sequence of devices and instructed fastening of devices and wire clamps) and satisfactory wire nut tightness.

ii. The Student Will answer 25 questions about electrical safety, devices, theory, practices, or equipment.

d. Machine (2018, 2019, 2020)

i. The student will identify the primary parts, safety features, observations (oil leak), or specifications on an identified type of machine/equipment related to the national Ag Mechanics Theme.

ii. The student will use an appropriate operator’s manual (provided at event) to answer pertinent questions covering safety features/warnings, specifications, manufacturing information, capacities, and other relevant information to the operation of the machine. The type of machine will be given in advance, but the specific model, etc. will be provided at the event.

3. ELIGIBILITY A. Grades 9-12.

B. Top 25% of total schools in a district qualify for the State CDE.

C. A team can compete with less than 4 individuals but will incur a deduction in points for the team score.

4. REQUIRED AND RECOMMENDED ATTIRE A. Required Attire

a. Safety Glasses b. Closed-toed shoes c. Long Pants, in good repair (NO holes or frays, etc.) d. Oversized or loose fitting clothing is dangerous, therefore banned (i.e. hoodies, etc.)

B. Recommended Attire a. Long or short sleeved collared shirt or coveralls

i. T-shirts are NOT recommended. ii. Official Dress is allowed, but is NOT recommended.


5. REQUIRED SUPPLIES AND EQUIPMENT Everyone will be given a safety briefing during orientation. Please observe all safety rules, and if you see something that doesn't look safe; let a competition official know. Teams will need to bring the following items with them: (each individual will need all of these things)

• #2 pencils for each person • Safety glasses for each person • Calculator (NO cell phones & NO graphing calculators) • Wire stripper • Flat screwdriver • Phillips screwdriver • Needle nose pliers • Diagonal Cutters • No knives allowed.

6. EVENT SCHEDULE A. Schools will be divided into two groups. Teams should plan to arrive and register not more

than 30 minutes prior to start time and not less than 5 minutes prior to start time. Each section should be completed within 2 hours and 45 minutes, start to finish.

a. Section I, including teams from ½ of the districts will start promptly at 9:30 a.m. b. Section II, including teams from the other ½ of the districts will start promptly at

1:00 p.m. c. Individuals will be divided for the 6 individual activities and rotate every 15 minutes.

(Approximately 15 contestants will begin at each activity table.) d. Every team will be together for one 25-30 minute activity. We will start with the first

5 school numbers (1-5) at the team activity and the rest of the contestants divided among individual areas. Every second rotation will bring the next 5 school numbers (6-10, etc.) to the team activity. After the team activity, students will return to their next individual rotation area from where they left off.

e. The Nebraska Agricultural Technology and Mechanics CDE takes place in the loading dock area inside Pinnacle Bank Arena. Participants should enter in the “Marshaling Door” on the north side of the building. Please be sure to note required and prohibited supplies and equipment before entering the Pinnacle Bank Arena.


7. ANNUAL THEME The annual theme is derived from the National CDE. The theme affects the contest specific machinery/equipment and the team component.

• 2016 - Animal Production Systems • 2017 - Material Handling Systems • 2018 - Processing Systems • 2019 - Plant Production Systems • 2020 - Integrated Pest Management Systems

8. EVENT FORMAT A. Team Activity:

All four team members from each team will work together and be evaluated as a team while solving complex, multi-system agricultural problems. The problem scenario is presented to the team on the day of the event and members utilize the materials and equipment provided to undertake and prepare a solution to the problem. Teams organize themselves, assigning duties and completing tasks together or separately depending on individual skills and abilities. Each team receives a maximum score of 150 points.’

B. Individual Activities:

Each team member will rotate through 6 individual activities with a maximum time of 15 minutes for each activity. Each individual team member will receive a maximum individual score of 50 points per station with a total individual score of 300 points. Individual activities are listed as follows:

a. Small Gas Engines (2018, 2020) i. Small gas engine part identification, tool identification and micrometer

measurements practicum. (Appendix A) 1. A total of 25 from the two lists and micrometer measurements will be

displayed ii. A 25 question test over small gas engines and theory. See Resources List

b. Hydraulics/Pneumatics (2019) i. Identify a total of 25 hydraulic/pneumatic symbols and hydraulic/pneumatic

parts from the lists provided. (Appendix B)

2. A switch, a light fixture, an outlet, and wire nuts will be available. 3. Competitors would strip the insulation to the correct length and

attach the wires to the devices for the competition. 4. The devices will not have to be tightened or grounded to the boxes,

rather left out to check correct procedures. 5. Sixteen boards will be laid out with 8 extra available during each

rotation to provide enough ready to use for each group. 6. Completed boards will be replaced with blanks, scored, and 'reset'

after each rotation. 7. A diagram will be provided at the activity.

ii. A 25 question test over basic electrical terms, safety, etc. is given. See Reference Materials.
